In 1820, George Pollard and Charles Ramsdell were rescued after 93 days at sea in a small whaling boat after a sperm whale charged and sank their ship in what would become the inspiration for the novel Moby Dick. The two men were found adrift, sucking on the broken long bones of their dead shipmates. What nutrients were they receiving by sucking on the bones?
A
Glucose and glycogen from the marrow.
B
Triglycerides from adipose tissue.
C
Protein and amino acids from epithelial tissue.
D
NaCl from the bone matrix.
Verified step by step guidance1
Understand that bones contain bone marrow, which is a source of nutrients.
Recognize that bone marrow is rich in adipose tissue, which stores triglycerides.
Consider that triglycerides are a type of fat that can provide energy when metabolized.
Acknowledge that while bones also contain minerals like calcium and sodium, the primary nutrient from marrow is fat.
Conclude that by sucking on the bones, the men were likely accessing triglycerides stored in the adipose tissue of the bone marrow.
